Показать описание
This time-lapse video sequence of Hubble Space Telescope images reveals dramatic changes in a ring of material around the exploded star Supernova 1987A.

The images, taken from 1994 to 2016, show the effects of a shock wave from the supernova blast smashing into the ring. The ring begins to brighten as the shock wave hits it. The ring is about one light-year across.

Discovered in 1987, Supernova 1987A is the closest observed supernova to Earth since 1604. The exploded star resides 163,000 light-years away in the Large Magellanic Cloud, a satellite galaxy of our Milky Way.

The ~31~ points that light-up are almost-all cloud protrusions inward in the initial ring—is there a secondary shock...

Wow!
But the light travels millions of years, how can we observe changes in space?
